Apollo Config vs Libreswan
A side-by-side editorial comparison of Apollo Config and Libreswan — release velocity, themes, recent moves, and the top alternatives to consider.
Apollo Config vs Libreswan: at a glance
What is Apollo Config?
Apollo 3.0 moves to Java 17 and pitches configuration management at AI agents.
Apollo ships a feature release roughly once a year with small patches between them. 3.0.0 in October moved the server to Java 17 and Spring Boot 4.1 and began what the project calls Agent First configuration management: structured APIs, user-delegated access and machine-readable capabilities for agents. The 2.5 line before it added incremental config sync and app-level export and import, followed by two permission and authentication patches.
What is Libreswan?
Libreswan patches four CVEs on two lines, two of them credited to Claude and Ada Logics.
Libreswan is an IPsec VPN implementation for Linux and the BSDs. On October 5 it released 5.4.1 and 5.3.3 together: 5.4.1 fixes three CVEs (null-pointer crashes on unexpected EAP and empty PKCS7 payloads, and a use-after-free on EOF in IKE over TCP), and 5.3.3 fixes the same three plus a FIPS certificate-leak denial of service. v5.4 in August remains the latest feature release, adding ML-KEM 768 post-quantum key exchange via RFC 9370.

Apollo Config
2.5DEVOPS
Apollo 3.0 moves to Java 17 and pitches configuration management at AI agents.
◆ Current state
Apollo ships a feature release roughly once a year with small patches between them. 3.0.0 in October moved the server to Java 17 and Spring Boot 4.1 and began what the project calls Agent First configuration management: structured APIs, user-delegated access and machine-readable capabilities for agents. The 2.5 line before it added incremental config sync and app-level export and import, followed by two permission and authentication patches.
◆ Where it's heading
After two years of lowering operating cost (single-process startup, incremental sync, export and import), 3.0 is the first release aimed at a new kind of client: software agents acting on a user's behalf. The platform bump to Java 17 came with it.
◆ Prediction
Expect 3.0.x patches on the new platform baseline; the entries do not yet show how the agent-facing APIs are used in practice.
Libreswan
5.0DEVOPS
Libreswan patches four CVEs on two lines, two of them credited to Claude and Ada Logics.
◆ Current state
Libreswan is an IPsec VPN implementation for Linux and the BSDs. On October 5 it released 5.4.1 and 5.3.3 together: 5.4.1 fixes three CVEs (null-pointer crashes on unexpected EAP and empty PKCS7 payloads, and a use-after-free on EOF in IKE over TCP), and 5.3.3 fixes the same three plus a FIPS certificate-leak denial of service. v5.4 in August remains the latest feature release, adding ML-KEM 768 post-quantum key exchange via RFC 9370.
◆ Where it's heading
Security response dominates the release history: 5.3.1, 5.3.2, 5.3.3 and 5.4.1 are all CVE releases, with 5.4 the one feature release among them. Recent CVEs credit AI-assisted audits, so the find rate may stay high while that tooling runs over the codebase.
◆ Prediction
Expect further point releases on both the 5.3 and 5.4 lines while 5.3 is still maintained. The entries do not show when a 5.5 feature release is due.
